1967 Buick GS 400

Buick's muscle car stopped living its little lie for 1967, and was the better machine for it. Gone was the 401-cid V-8 that had masqueraded as a 400-cid mill. In was a genuine 400-cid V-8 (well, actually 399.748 cid), and the occasion was marked by a change in name, from Gran Sport to the 1967 Buick GS 400.
